Jessica Simpson’s father reportedly blasted John Mayer in a furious phone call.

Joe Simpson is said to have lambasted the ‘Gravity’ singer over his recent comments to Playboy magazine – in which he described the singer-and-actress as “sexual napalm” – and warned him never to contact, or even speak about, the blonde star ever again.

A source said, “Joe took it upon himself to call John up directly for a ‘man to man’ discussion. Joe didn’t tell Jessica ahead of time because he knew she’d object. The conversation was pretty one-sided. Joe told John that he best not even think of uttering Jessica’s name again. John put up a feeble defense – he tried to reason with Joe that he was praising Jessica, not insulting her. But no father wants to hear from an ex-boyfriend about how hot his daughter is in bed – and Joe told John as much. Joe told John to stay away from his family and man-up and apologize for his comments.”

John – who dated Jessica for nine months until May 2007 – has reportedly attempted to make amends with his ex-girlfriend, but his efforts have so far been unable to win over her protective dad.

The source added: “John did email Jessica and tell her he was sorry if the interview offended her. But regardless of whether Jessica is willing to forgive and forget – Joe Simpson isn’t ready to make amends. He’s holding a massive grudge against John. But there’s no reasoning with Jessica’s dad. He didn’t like John when Jessica was dating him and likes him even less now.”

The only person Papa Joe is ever concerned about is Papa Joe. The whole situation sucks all-around for everyone involved and the truth of the matter is that John Mayer is probably beating himself up worse than anyone else could do.

Jessica is a grown woman. She can handle herself, and has done so with aplomb. The best thing that could happen to her is to wake up and realize that the king is pouring poison into her ears…and boot Papa Joe and his “management” to the curb.

Papa Joe praised John when he was with Jessica. Now he “never liked him.” Come on, media. Get the story straight.

As for John, he’s shutting up and playing his music, which is the very best thing he could do right now. If you want to know how he’s doing? Go see a show.
